The term codec comes from composedwords compressor-decompressor or coder-decoder. Codec normally get thefollowing 3 tasks: Decoding - EncodingDecompression - Compression Decryption - Encryption Decoding- Encoding When you call through normal PSTNphone, your tone is transmitted over the telephone line. But with Voice over InternetProtocol, your voice is changed into signals. The conversion is calledencoding, and is obtained by a codec. When the digital voice goes to itsdestination, it needs to be decoded back to its original state so that thecorrespondent could understand and hear it. Decompression- Compression Bandwidth is a limited commodity. So,if the file or data to be sent out is created lighter, you could send more in aparticular time amount, and thus enhance performance. To make the voice less massive,it is packed together. Compression is a difficult procedure whereby the similardata is saved but making use of lesser space. Throughout compression, the fileor data is saved to a structure proper to the algorithm of compression. Thecompressed file is sent to the network and once it goes its destination, it isdecompressed to its original state before decoding. In a lot of cases, but, itisnt needed to decompress the file back, because the compressed file is in aconsumable condition. Decryption EncryptionEncryption is the best tool forachieving protection. It is the procedure of changing the data to such a statethat no one could understand. In this way, if the encrypted file is stopped byunauthorized individuals, the data still stays confidential. Once the encryptedfile reaches the destination, it is decrypted to its original state. Usually,when the data is compressed, it is encrypted to a specific extent, because itis changed from its original state.
